While running the MCAA’s Fastest Trowel Contest…
I ran the MCAA’s Fastest Trowel Contest in Las Vegas for many years, and judging the competitions required accuracy and consistency. This is the type of measuring device used by masonry contest judges to determine scores at the masonry competition.
This scale can be used in conjunction with a mason’s level to determine plumb and level. The level is placed on the wall and the judge attempts to slide the scale between the level and the masonry to check for accuracy. The scale measures a void depth if present.
